FORT SMITH (AP) — Authorities in eastern Oklahoma are searching for a plane that disappeared while flying from Arkansas to Oklahoma.

LeFlore County Sheriff Rob Seale told the Times Record on Wednesday that search crews are looking in a heavily wooded area of the Ouachita National Forest in southeastern Oklahoma.

Seale says the search began Tuesday after the Federal Aviation Administration contacted the sheriff’s department and said 71-year-old Elmer Ray Broadbent and his Piper 28 aircraft disappeared while flying from Searcy to Elk City.

Seale says an Oklahoma Highway Patrol helicopter is being used in the search.
